Caltha.

CALTHA, L. Marsh Marygold, Meadowbouts, Cowslip. (The real cowslip is Primula. -Henriette.) Several species, all acrid when fresh, not eaten by sheep; they kill the cattle bruising them, inflaming their stomach: yet Cutler says that they are a good pot herb boiled; see Ranunculus. The flower buds are similar to capers when pickled. The juice stains yellow. Said to be equivalent of Chelidonium.
